This invention relates to doors generally and contemplates more speciically, for :ap-

plication to side slide doors of railway house Y cars, means for elevating'said'doors. p a It is an object ofthis invention to provide door elevating means in which an operating handle yis employed, said handle` being positioned preferably adjacent the vertical edge ofadoor. 3

A further `object is the lprovisionvof door elevating means-1in which unauthorized elevation of a door when in closed, latched position is prevented. y l

It is `an object, also, to associate the operating handle of doorelevatingmeans with the usual latching mechanism ofthe door so that said'latching mechanism may be utilized to prevent unauthorized lifting of the door when said mechanism is inoperative position.

An object resides in the arrangementv of door elevating means inwhich thelelevatiig force is communicated to the door to effect elevation thereof at the remotest point possible consistent with practical considerations.

An object, as well,` is `the provision of a stationary operating handle secured to the door and-provided with stop means adapted to limit kthe movement vof door elevating means, whereby aportion of said elevating f` means and said stationary .means maybe grasped by the operatorpto move the door.

Other objects and` advantagesl will become apparent as the description of theinvention proceeds, taken in connection with the draw- 5 ings forming a partof the specification and in which similar numerals refer to similar Y ing legs inV 'abutting relationand riveted together through said legsfln Vthe endsof Y each *of the runwaysis positioned and fastened a bracket member 18, 'preferablyin parts throughout.

The lug adjacent the forward edge of the door co-acts with an operating lever 22 to transmit the force applied to said lever to the runway to effect rotational movement thereof in order to elevate the door. rIhe lever 22 is provided ,withv a cam portion 23, adapted to Contact with the lug 21 and with a handle 24 by which the lever may be convenientlyV operated. The lever is mounted for pivotal movement in a plane parallel to the door upon a hub 25 provided on the casting 15.

Secured to the door 10 is a stationary handle 26 provided with a projection 27 positioned slightly above the handle 26 and f with which the lever 22 is adapted to contact when a downward pull is exerted thereon, to e'levate the door. 'Iheprojection 27 thus supplements the lug 21 in assuring apositive limit of rotational movement of the runway 12.

In order to prevent tampering with the elevatingmechanism and to avoid raising the door when the latter is in latched operative position it is desirable to secure the operating levers 22 against movement. A

construction for accomplishing this beneficial result is illustrated in Figure 4 of the drawings. In this form each of the levers 22 is provided with a lobe 28 to which is pivoted one' end of a hand or main door is provided with a pair of spaced projections 30, 30 and the link on the left hand or auxiliary door is provided with only one proection adjacent the upper end of the link.

ecured to the right hand door is a hasp fastener 31 on which is pivotally mounted a hasp 32 adapted to be secured to the left hand door when both doors are closed by the usual pin and staple arrangement carried by a'bracket 33 secured to the left hand door. The links 29 are adaptedto liefbetween the doors and the hasp 32 with the extensions A30 adjacent ,the upper end ofsaid links lying upon said hasp. It is apparent that in this position with the doors closed and sealed, downward movement of ,A lug 34 is provided on each adapted to control the movement of its associated link 29 through contact therewith and,

"referring tothe right vhand door, the link 29 will in turn, by means of the projections' 3() on said link, control themovement of the hasp 32 when the latter is released in order to open the doors. Upon its release the hasp will'move downwardly about its pivotal connection with the hasp fastener 31 and lie between the projections 30. In this position -of the hasp itwill clear the lug 34, which is link 29. The link on the right y of the castings 15 secured vto the doors'. This lug is doors are closed and the levers released the latter will move upwardly. During this upward movement the links 29 will also move upwardly under the control of the lugs 34 and, in view of the fact that the hasp 32 lies between the projections 30 of the right hand link 29, said hasp will also be guided toward Voperative position. Itis to be noted that the lugs 34 will effect a progressive change in the angular relation of the linksy 29 'relative to the lever-S22 so that at no time during the downward or upward movement ofthe levers will the links extend beyondY the adjacent edge of their respective doors. By this arrangement damage to theV 'links is avoided. y 'f In Figure-6 there is illustrated` a modified lever construction which, however, incorporates an arrangement preventingoperation of said levers when the doors are latched 4in `their home position. In this construction the links 29-are dispensedwith and the levers 35, 35 are arranged substantially vertical to ing levers positioned adjacent the rear edges of the doors. The operating levers -are adapted to operate in a plane parallel to thedoors.

VFigures 7 and 9 illustrate a lmodified, door elevating construction. vIn this modification the elevating means includes the runway 12 eccentrically connected to the door adjacent its ends. In addition thereto the door 10 has rigidly secured to ita member 36, preferably in the form ofla casting or forging, to which an operating lever 37 is' pivotally attached.V The casting or forging is shown.

positioned substantially centrally of the door but it is to of the door. The member 36 is provided when the door is lowered. Carried by the runway 12,7either vby means ofiriveting as sliown,'by welding or by an integral formation is anV outwardly extending lobe 39, the upperV Y surface of Iwhich is preferably rounded .and which is adapted to-transmit the downward pressure of the'handle 37 into a rotational movement of' the runway to lelevate the door. It is apparent, .in .this

modification, that the lever operates in a plane parallel to the door and'tliat, if de .sired, the stationary handle 26 may readily be employed with the lever 37 in the m-anner set forth in the description of Figures 1 to 3, inclusive, lof thek drawings. ,It -is to be noted also that by transposing the castings 36, ,to-1

gether with their Y.levers 37, and lobes 39 `from one` door to the other these castings may, without change, be positioned adjacent the lower corners of the doors whilelvavoiding the undesirable feature of having thebe observed that-the handle 37 extends to a point adjacent the forward edge iso Y Vclaims appended hereto.

levers extending beyond the forward edges.

by movement in a plane parallel to the door. 'It is to be noted that'by offsetting the levers as shown at 41, 41 they may be made vto extend and be latched behind the haspv 32.v

A further modied latching arrangement for an operating lever, Capable of movement in a plane parallel to the door, is shown in Figure l0 applied in this instance to a single door house car construction. A llever 42 is provided preferably cast integrally therewith with a lug 43. A bracket 44 secured to the door carries a lug 45 provided with an opening aligned with an opening formed in the lug 43, together order to secure the lever 42 it is only necessary to swing the hasp 47 sothat the staple 46 extends through an opening therein and to pass the locking pin 48 through the aligned openings in the lugs 43 and 45 and in the staple. at 49. Y n

VThe. operation of the elevating means Vof the invention is believed clear from the foregoing detailed description. When the operating lever vis pulled downward the cam portion 23 of the lever forces the lug 2l down.- wardly, producing a-transverse rotation of the runway l2 about the rolling elements l1 as` fulcrums. of the runways the doors will be elevated by the eccentric connection between the runways and the doors'provided by the Vtrunnion 19 on the member 18 secured to the runway and the bearing 2() formed in the bracketpl se.

cured to the door. This mode of operation remains the same with each form of operating lever disclosed.

It is to be understood that the door elevating means may be used either with double doors of house cars or with single doors therefor and that the doors shown are merely for the purpose of illustration and are not to be construed in any manner as limiting.

It is evident that many changes in details'V may be made without departing from'the spirit of the invention as dened by the I claim:
